    An add-on kit with a barge tow with riprap or coal and another with rails.  There was a while here when tows with rail cars were transported over to the Delmarva peninsula more or less continuously.

    Jaager got a reaction from Bill Morrison in Red Jacket by MrBlueJacket - FINISHED - BlueJacket Shipcrafters - Scale 1/8" = 1' (1:96)   
    I bought the Sea Gull plans for Red Jacket and started the lofting.  The plans are 1/8" : 1'.  I loft at 1/4", but man! this is a huge ship.  The hull at the main deck is close to 250 feet long.  I do 1:60  and while anyone mad enough to build her at 1/4" would start with a 5.2 foot long hull less spars,  at 1:60 , it is
    a daunting 4.2 foot beast. 
    Wm Crothers' plans are still available - they are pretty detailed, but since they are drawn to support both solid hull and POF, I would not be surprised if Blue Jacket did not use Crothers as a basis for their plans.  Red Jacket has specific entries in his The American-Built Clipper Ship.
     
    You will have quite a project there even at 1/8" scale, which is close to being in the miniature realm .
    Wood Craft has some pretty thin veneer of Maple, Cherry and other species that scale to 1:96 OK,  so might consider planking the hull and choosing an anti-fouling paint color wood for the submerged part of the hull.  This would add additional time for the build.

    Jaager got a reaction from catopower in Blue holly: can it be saved?   
    I harvested and cut into billets some Holly from a cousin's land.   When I rip cut it water almost squirted from the end as the blade pushed it.  This told me two two things:  Holly contains a lot of water.  Holly pore channels are highways.   Blue mold will out race you unless the Holly is harvested in Winter and unless the cut ends are sealed and the wood immediately goes into a kiln.  I did not wish to case harden my supply, so I set the temp in my foam box to be just a bit higher than what I thought a fungus could survive.
    The strain of Holly on my cousin's wood lot is yellow, not snow white.
     
    From my traditionalist perspective, you are not in trouble at all!
    No species of wood used for an actual ship was snow white,  so the color of Holly that is sold does not fit a ship model.
    The yellow - or blue - or grey (which is what some of my infected stock is) is actually more appropriate.
    The Blue Mold fungus does not affect the structural integrity of the wood.  Holly is neigh on to perfect for us.  It works for part quite well and for planking, nothing else bends quite as well. The grey or yellow would closely match the color of an actual deck - Sun bleached and salt water abuse.  For tar foot prints and drips from standing rigging additional color is needed.  The snow white decks planked with marquetry Holly is flash and not realistic.
    Holly readily takes a dye.  Perfect for black wales.  The blue will probably want a dye if you paint with wood.  Alcohol based aniline dyes -  I do not see that the additional depth from water based aniline dyes would show at model scales.  It would just add a grain swelling problem and a longer drying time.
     
    Unless you are dead set on having it be snow white - you are golden.   Holly over here is now absurdly expensive.  I suspect sawyers trash or burn infected or off color Holly.  Would that I could contact one and take what he thinks is trash off of his hands.

    Any of the four varieties of PVA: white, yellow,  yellow water resistant, yellow water proof  - produce a bond that is similar in strength - not enough difference (if any) to shelve what you have now.  With any of it    the wood will probably tear apart at the bond before the PVA gives way.
    I have the thought that Gorilla yellow is Tightbond II with a different label.  Gorilla white is probably Elmer's white, Titebond clear with a different label. 
     
    The significant difference with PVA is  the more resistant to water it is the more acidic it is 
     
    white = pH 4.5 - 5.5
    I =  pH 3.5-4.5
    II = pH 3.0
    III =  pH 2.5-3.5
     
    Not any water when dry - so no hydrogen ions crashing around -  It will out gas acetic acid but so do some species of wood - which is only something to consider if the model is in a case with no ventilation or if there are fittings with Lead as part of the mix.

    Another two widely separated schools of practice.
    Old school - polyurethane is glossy plastic - too thick -  modern synthetic -   preferred universal primer and overcoat is:  shellac
    New school - poly is the go to.
     
    The CA to poly works because CA will bond to a smooth surface.  But the bond is only as strong as the poly to wood bond.  Pull on it and the poly layer will go with the CA side.
    PVA to poly - no bond  -  poly is glassy smooth -  PVA needs tooth, pores, an irregular surface - something that its invasive chains can wrap around or bore into.

    Gorilla glue  is about the worst brand name that you could present as far as determining exactly what type of glue is being discussed.  Given the wide range of products with the name Gorilla, and the probable toxic and hazardous chemical synthesis involved, my guess is that most of their stuff is from core chemical companies - packaged and sold under various brand names - Gorilla being one of them.
     
    The original Gorilla glue - the foaming polyurethane is something to be absolutely avoided for a wood model.
    I see three types of Gorilla brand PVA -
    white -probably the same as Elmer's - and maybe Weldbond (really imaginative and enthusiastic ad copy writers)  dries clear
    yellow wood glue - looks like Titebond II  water resistant  dries amber
    yellow wood glue ultimate  -  looks like Titebond III yellow - water proof  dries amber  the original Titebond III is brown and dries darker
    They sell various flavors of CA.  I do not use any type of CA  - but from from discussions here - quality of the brand is probably very important - economy or generic CA is a way to get a poor result and a lot of waste.
     
    There seems to be two camps here as far as CA as using an adhesive.
    1. Avoid at all costs - old school    toxic, perverse, very poor shelf life after opening  ----   wood to wood: PVA   wood to metal: two part epoxy   natural fiber rigging: bookbinders pH7 PVA 
    2. Greatest thing available.
     
    Then there is always one of the hide glues especially the hot pot flakes - if you wish to replicate 17th-19th century practice.

    You wrote "scanner".    Since you are only doing this the one time, I am suggesting that low tech and more time consuming may be a more practical option.
    Now that I re-read what I wrote - maybe "L" shape is more accurate. The boat gets in the way of the inside leg of a "U".  Maybe just high enough to butt against the keel.
     
    Look at a set of lines for any vessel.  Profile,  Plane (WL),  Body . 
    Now, for traditional POF - the Body plan is almost irrelevant.  The most important is WL.   The profile has the buttock lines - which are only really useful at the ends.
     
    The Body plan is the cross section at each station. *   The stations are the midline of a bend.  (A bend is a pair of frames with overlapping butts.)  A Hahn style framing (plot the outside shape of every other bend) does not need the shape at the midline.  A loft every frame method can use a station shape - but there are 200-400 shapes and maybe 24 station shapes - so only a little helpful.
     
    For a boat, built using a mold plug,   The Body plan is 90% of what is needed.   You need to replicate the Body plan - using as many station intervals as you think that you will need. 
    You need a jig to measure the cross section at every station.   A wooden X-Y graph.  Like a piece of graph paper- but 3D.   And able to move along the Z axis.    The keel is X=0  Y=0.     You need to measure X at Y=1',  Y=2' , Y=3'......     maybe at 6" intervals is you are compulsive.   You need a fixed, known distance Y  outside the widest part of the hull - so that the graph will fit.   The longer than a  yard stick (with a line level bubble) sits at Y=1' and how far it is from the keel is the X value there.  You could drive a fence post at every station interval, but a movable jig seems more practical.
     
     
    * The mold loft used the Body plan.  They expanded the 1:48 drawing to a 1:1 chalk line on the floor of a barn sized room.  Made patterns from that shape and added marks for the lines of the frames between the stations.  200 patterns - one for each frame - would have been insane.  Besides, the shipwrights that actually shaped the frames would not have been pleased about being told how to do their jobs by the mold loft gang.  Now, when frames became iron and then steel, an adz does not work so well. (I use a method that mimics the mold loft.)

    Micha,
     
    Ask Rassy for a table of offsets.  - it is not an America's Cup candidate. 
     
    High tech is not necessary.  A jig made from 2x4's  - A "U" shape (without the rounded corners)  to site the keel and be perp. and a sliding yard stick. 
    Get the NRJ CD's and find the older articles on taking off lines from a half hull model.  Except getting a pantograph tracing of the cross section curve
    would be too large (unless you figure a way to make an actual reducing pantograph of it).  Or, or .  do they make laser line levels that measure the distance?
    Then it is just a matter of writing down some numbers show on a screen -  like the stick version without the interpolation.
     
    In your place, I would just go to school on all this - making sure my bites were not too ambitious and then when I felt confident enough to scratch build a modern luxury yacht model, pick one that does have available lines.  Then show Magnus Rassy the celebration of his design that he missed.  If you have not caught an entirely different bug - after you have gotten a deeper view of the possibilities in all this.

    I checked on Amazon.   AM Arrowmax  offers a small spectrum  of variations,  none of which intersect with my needs. Mostly it is mutually exclusive for the 50-80 wire gauge drill bit function.  Speeds and tool attachment are discordant. The models with a chuck that allows infinite diameter bits do not have the speeds that I require.  The ones with the speed have a fixed size insert.  There is even one with 10,000 to 30,000 RPM if burning a hole instead of drilling one is an aim.
     
    The drill bit sets with a fixed size base are usually carbide - not HSS.  Most of what we do involves the possibility of "Parkinson-like" twitches.  HSS has flex, carbide does not.
     
    Reading the reviews - red flags - lots of red flags - the quality of the materials and the gauges of the wires - I fear planned obsolescence and short term obsolescence at that.

    Jaager got a reaction from allanyed in Hull Plug for a mold (reproduction of the hull maybe)   
    Micha,
     
    Ask Rassy for a table of offsets.  - it is not an America's Cup candidate. 
     
    High tech is not necessary.  A jig made from 2x4's  - A "U" shape (without the rounded corners)  to site the keel and be perp. and a sliding yard stick. 
    Get the NRJ CD's and find the older articles on taking off lines from a half hull model.  Except getting a pantograph tracing of the cross section curve
    would be too large (unless you figure a way to make an actual reducing pantograph of it).  Or, or .  do they make laser line levels that measure the distance?
    Then it is just a matter of writing down some numbers show on a screen -  like the stick version without the interpolation.
     
    In your place, I would just go to school on all this - making sure my bites were not too ambitious and then when I felt confident enough to scratch build a modern luxury yacht model, pick one that does have available lines.  Then show Magnus Rassy the celebration of his design that he missed.  If you have not caught an entirely different bug - after you have gotten a deeper view of the possibilities in all this.
